WARNING: Injury Hazard
All installation procedures must be performed by qualified personnel with full knowledge of all
applicable electrical and plumbing codes. Failure could result in prope rty damage and
personal injury.

WARNING Electric Shock Hazard

Brewer must be properly grounded to prevent possible shock hazard. DO NOT assume a
plumbing line will provide such a ground. Electrical shock will cause death or serious Injury.

WARNING: Burn Hazard
This appliance dispenses very hot liquid. Serious bodily injury from scalding can occur from
contact with dispensed liquids.

This appliance is intended for commercial use only.

INSTALLATION

READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION

IMPORTANT:

To enable the installer to make
a quality installation and to
minimize installation time, the
following suggestions and tests
should be done before the
actual unit installation is started:

CAUTION:

EQUIPMENT DAMAGE

DO NOT plug in or energize this
appliance until all Installation
Instructions are read and
followed. Damage to the
Brewer will occur if these
instructions are not followed.

CAUTION:

UNSTABLE

EQUIPMENT HAZARD

It is very important for safety
and for proper operation that the
brewer is level and stable when
standing in its final operating
position. Provided adjustable,
non-skid legs must be installed
at each corner of the unit.
Failure to do so will result in
movement of the brewer which
can cause personal Injury and/
or damage to brewer.

NOTE: Water supply inlet line
must meet certain minimum
criteria to insure successful
operation of the brewer.
Bloomfield recommends 1/4"
copper tubing for installation of
less than 12 feet and 3/8" for
more than 12 feet from a 1/2"
water supply line.

REFER TO EXPLODED VIEWS PAGES 18 thru 22 FOR
COMPONENT NAMES/NUMBERS

Unpack the unit. Inspect all components for completeness and
condition. Ensure that all packing materials have been removed
from the unit.

Verify that the Spray Head Gasket and Spray Disk are properly
installed.

LEVELING THE UNIT

Verify that an adjustable leg is installed at each corner of the
brewer, and that a rubber foot is installed on each leg.

Set Brewer in its operating location. Level the Brewer. A spirit
level should be placed on the top of the unit, at the edge, as a
guide when making level adjustments.

Level the unit from left to right and front to back by turning the
adjustable feet. Be sure all four feet touch the counter to prevent
tipping.

PLUMBER’S INSTALLATION INSTRUCTIONS

IMPORTANT: This equipment must be installed to comply
with all applicable federal, state and local plumbing codes and
ordinances; specifically:
The Basic Plumbing Code of Building Officials and Code
Administrators International, Inc. (BOCA) and the Food Service
Sanitation Manual of the Food and Drug Administration (FDA).

Brewer should be connected to a POTABLE WATER, COLD
WATER line. Flush water line before connecting to Brewer.

DO NOT use a saddle valve with a self-piercing tap for the water
line connection. Such a tap can become restricted by waterline
debris. For systems that must use a saddle tap, shut off the main
water supply and drill a 3/16” (minimum) tap for the saddle
connection, in order to insure an ample water supply. Remember
to flush the line prior to installing the saddle.

The brewer must be installed on a water line with average
pressure between 20 PSI and 90 PSI. If your water pressure
exceeds 90 PSI at anytime, a pressure regulator must be
installed in the water supply line to limit the pressure to not more
than 90 PSI in order to avoid damage to lines and solenoid.

A water shut-off valve should be installed on the incoming water
line in a convenient location (Use a low restriction type valve,
such as a 1/4-turn ball valve, to avoid loss of water flow thru the
valve.

913 75937 Owners Manual McDonalds Decanter Brewer 8718 & 8738

INSTALLATION (continued)

The water line must terminate in a 3/8" MNTP quick-disconnect
fitting, which will connect to the provided flex line. See Figure 2
below.

Fig. 2 Water Supply Installation

In some areas, local codes require a backflow preventer (check
valve) to be installed on the inlet water line. If a backflow
preventer is used, you must install a water hammer arrester in
the incoming line, between the backflow preventer and the
brewer inlet, as far away from the brewer as space will allow.
This will relieve the excessive back pressures that can cause
faucet leaks and solenoid malfunctions.

ELECTRICIAN’S INSTALLATION INSTRUCTIONS

REFER TO ELECTRICAL SPECIFICATIONS - Page 1
Check the nameplate to determine correct electrical service
required for the Brewer to be installed.

IMPORTANT: Before connecting to electricity, make sure
automatic brewers are connected to the water supply and tank
is filled.

Remove front panel to access terminal block.
Model 8717 requires a 120/240 volt 3-wire (L1, L2, Neut) plus

Gnd 30 amp circuit.
Model 8737 requires a 2-wire (L1, L2) plus Gnd 30 amp circuit.
Flexible conduit is recommended for electrical connection to

allow brewer to be moved for cleaning underneath.
Flexible or rigid conduit must be connected to the brewer with a

suitable strain relief (provided by electrical contractor).

WARNING:

SHOCK HAZARD

Brewer must be properly
grounded to prevent possible
shock hazard. DO NOT
assume a plumbing line will
provide such a ground.
Electrical shock will cause death
or serious injury.

IMPORTANT:

Supply power must match
nameplate for voltage and
phase. Connecting to the
wrong voltage will damage the
brewer or result in decreased
performance. Such damage is
not covered by warranty.

IMPORTANT: Do not connect
brewer to electrical power until
you are ready to fill the tank.
See instructions on page 6.

IMPORTANT: The ground
lug of the brewer must be
connected to a suitable building
ground.

OPERATION

Fig. 4 Brewer Operation Diagram

IMPORTANT:

Tank must be full of water
before connecting brewer
to electrical power.
Heating elements will be
damaged if allowed to
operate without being fully
submerged in water.
Damage caused by
operating the brewer
without water in the tank
is NOT COVERED BY
WARRANTY.

A. START-UP

For initial start-up, or if the brewer has not been used for an
extended period of time:

♦ Be sure spray disk and brew gasket are properly installed in the
brew head.

♦ Be sure the water supply is properly connected and the water
supply valve is turned ON.

♦ Be sure the WATER TANK IS FILLED
BEFORE energizing the tank heater THE WATER TANK MUST

BE FILLED. Place an empty decanter under the brew head. With
the TANK HEATER SWITCH OFF, press the START BREW
SWITCH. Run at least three full brew cycles, or until water
flows from the brew head. When water stops dripping, empty the
container.

Once the tank is full of water, press the TANK HEATER SWITCH
to ON. The heating elements will begin heating the water in the
tank. When the water has reached the proper temperature, the
“READYTO BREW” light will go glow.

WATER HEATER

Water temperature is sensed by a
thermobulb inserted into the water tank. This
temperature signal is fed to the thermostat,
which controls line power to the heating
element.

The setpoint temperature is adjustable at the
thermostat.

The element is protected from over­temperature by a hi-limit thermostat.

WATER FLOW

AUTOMATIC OPERATION

Pressing BREW button energizes the
solenoid valve, allowing water from an
external water supply to flow into the basin
pan and then into the hot water tank. This
forces an identical amount of hot water out
of the tank and through the spray head into
the brew chamber

The solenoid uses a flow control device so
that flow is consistent between 20 p.s.i. and
90 p.s.i.

Length of time the solenoid is open is
controlled by the timer.

HOT WATER FAUCET
The faucet water coil is submerged in the hot

water tank and draws heat from the brew
water. Water going to the water coil is not
controlled by the solenoid valve.

The faucet is at supply water pressure any
time the faucet shut-off valve is OPEN.
